Bitlocker management client internet

Recommended Posts

Hello,

I installed MBAM on my SCCM server without problem.
Everything works properly locally.

I deployed a server in DMZ to be able to manage my clients on the internet.

When I deploy Bitlocker via the local everything works, I have the Bitlocker window that opens to activate it.

When I deploy bitlocker on a computer located on the internet, I have no window that opens and I have this in the logs:

Unable to find suitable Recovery Service MP

I use SCCM 1910

Thanks

Unable to find suitable Recovery Service MP  usually means that it cannot communicate with the https enabled management point, are you using pki on your clients and sccm server(s) ?

I just found this on my server in DMZ:

Maybe it's related

Can I send you the logs in MP?

that does look related, does it correlate to when the client was communicating with the mp ? if you want to zip logs and email them to me then fine, send them to niall AT windows DASH noob DOT com

Hello,

I still have the error cited above in DmpDeviceCertAuthModule.log but this does not correspond to the moment when I evaluate the conformity of bitlocker.

The mpcontrol.log of DMZ server indicates the SSL is enabled.

Have you been able to see my log file?

Thank you
